[Zope] ZMySQLDA

Hi, can anyone give me a link to a How-To for installing ZMySQLDA. Tried several but always get this one: Traceback (most recent call last): File "D:\ZOPE\lib\python\OFS\Application.py", line 558, in import_product product=__import__(pname, global_dict, global_dict, silly) File "D:\ZOPE\lib\python\Products\ZMySQLDA\__init__.py", line 91, in ? import DA File "D:\ZOPE\lib\python\Products\ZMySQLDA\DA.py", line 91, in ? from db import DB File "D:\ZOPE\lib\python\Products\ZMySQLDA\db.py", line 89, in ? import _mysql ImportError: _mysql: init failed TIA Frank
